Thisinvention'relates to theal pl c tionofcard clothing to the surfaces of drums. cylinders or rollers as used in cotton or woolloards or for-other similar purposes.

The card clothing for suchcylinders issupplied in long, narrow belt-like strips andis helically] wound on the cylinder under heavy and continu .ous tension. In the usual practice, this tension may he on the order of 300 toAOOpoundsf Itlhas I been the regular procedure to turn the cylinder manually against this heavy tension; with unavoidable delays and substantial variations in It is the .general object eliminate this slow and expensivemanual' opera:- tion' of covering mechanism; and 'to provide power of myinventioriito p s means to turn the cylinder or drum continuously and at a uniform rateof speed, and which power ineans is not markedly responsive to adjusjtmentv ,oicovering tension. i

To'the accomplishment of this gen alfbbiect, one feature of the invention relates to"the"provi-' 'sion of convenient and effectivepower means for rotating the drum'andfeeding the'tensi on device 'in "timed relationand'both-from the same motor- A' further feature "relates to a novel construction by which the mechanism e-snares.

Referring to the drawings, I have shown a cylinder or drum C (Fig. 1) having a drive shaft l0 and assumed to be mounted in and to form a 1operatesit0 effectabrupt stopping or-izthe motorrM.

The base plate 50 is suspended from the supporting shaft 62 by hangers 65 (Figs. 1 and 4). Each hanger 65 is provided with an inclined upper notch 66 (Fig. 4) and with an inclined lower notch 61, and also with a stud 68 by which it may be secured to the base plate 50.

When the parts are in the position shown in Fig. 1, thef hangersfiifi have their upper notches 6B engaged with the supporting shaft 62, the hangers being held from axial displacement on the shaft by collars i and H (Fig. '7). a stud 74 adapted to extend into a small hole 'l5 (Fig. 4) above a notch 66 or 61 of'ea'ch hanger cylinder C.

Each collar H ha'sj. 3'

and thus prevent upward or angular displacement l of the hangers when power is applied to turnthe.

When the parts are in the position shown tint:

Fig. 1, the motor M is substantially displaced toward the observerf and will'not interfere with the mounting of the wornigear' 22 andfit's casing 24 onfthe vend of the cylinder shaftlil and in reasonably close relation tothe drum or cylinder C 7 I IL, however, it should be necessary o'r dje'sirable to mount the worm gear on the opposite end ofthe cylindershaft I 0,th e position of themotor parts,by reason of its ofiset position,

The hangers 65 are also removed and reversed v with respect to theplate 50.

; iI then' use the lower notches :61 in thehangers 65 for engagement with the supportingshaft 62.

-Having-described the detailsof construction of my improved 'coveringmechanism, it will. be seen that the mechanism is simple and reliable; that it may be readily attachedto a cylinder shaft for eitherfaright-handor a left-handdrive; that i continuous poweranduniform speed is provided for-thecylinderC; and that a similarly continu- -ous and; uniform .feed is .PI'OVidEd', for the feed shaft.ofi-thettension, device T..'

By the use of my improved covering mechanism, the time required to cover a cylinder is due to fatigue. Furthermore, both the speed and the tension are much more uniform and consequently the card clothing is applied in such manner as to give improved service.

'; Having thus described my invention and the advantages thereof, I donot wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is: 1. Inca covering mechanism for a cylinder having'acylinder shaft, in combination, a worm gear attachable to either end of said cylinder shaft, a wormforsaid gear, aworm shaft for said worm, a power driving 'unit, a driving connection between said driving unit and said worm shaft, and
